On the official 2oneday fansite, Jaebeom, the leader of 2PM announced that he will be officially quitting 2PM.
Jaebeom will be leaving Korea today at 6:30pm KST.

What Jaebeom posted:

“Hello, I’m 2PM’s Jaebeom.
I’m sorry for giving you my last greeting through this letter.
I think it will be hard for me to see you all on stage because of my sorry heart.
I’m really sorry to everyone, and I’m even more sorry to the fans who have shown me love.
From today, I will leave 2PM.
2PM boys, I’m really sorry to the boys and I’m sorry I couldn’t be strong as a leader and a hyung and have to leave like this.
However, I hope you will be more cool and charming.
Again, I’m sorry.
